ABSTRACT:
A canister auger of inexpensive construction is provided by forming the handle and canister of molded plastic parts, so that only minimal portions of the assembly require metal parts. The construction and design provide effective bearings between the canister and the handle. The canister is formed by a pair of molded shells which are secured together by fasteners. The clamp for engaging the auger wire utilizes a thumb screw and standard nut of metal cooperating with plastic parts in such a manner that effective operation, at reduced cost of parts, is achieved.
